Facebook climbed from a YouGov rating of 2 in the weeks of June 1-15, to 17.5 in June 16-30. To put things into perspective, YouGov's ratings span from -100 (completely negative) to 100 (completely positive). Is it going to be 100 percent accurate? No. But it does fall into line with what's been pretty evident on an anecdotal level--that Facebook has weathered yet another momentary PR fiasco.
